PHP Operators

The most common PHP operators are assignment operators, arithmetic operators, combined operators, comparison operators, and logical operators. Each type is discussed separately below.

Assignment Operators

The basic assignment operator in PHP is "=". This means that the operand to the left of "=" gets set to the value to the right of "=".

Arithmetic Operators

Operator	Example	Result
+	4 + 2	6
-	4 - 2	2
*	4 * 2	8
/	4 / 2	2
%	4 % 2	0
++	x = 4; x++;	x = 5
--	x = 4; x--;	x = 3

Combined Operators

You can combine an arithmetic operator with the assignment operator to form a combined operator. Combined operators are shown below:

Operator	Example	Meaning
+=	y += x	y = y + x
-=	y -= x	y = y - x
*=	y *= x	y = y * x
/=	y /= x	y = y / x
%=	y %= x	y = y % x

Comparison Operators

Operator	Meaning
==	is equal to
!=	is not equal to
>	is greater than
>=	is greater than or equal to
<	is less than
<=	is less than or equal to

Logical Operators

Operator	Meaning
||	or
&&	and
and	and
or	or
xor	xor
!	not
